Problems solved by technology

[0005] The purpose of the present invention is to address the characteristics of long-term large-scale and unreasonable application of chemical fertilizers, slow effect of organic fertilizers, serious shortage of application area and dosage, low efficiency of biological bacterial fertilizers, small application scale, no regional pertinence, and difficulty in marketing. In order to solve the problem of inconvenient mechanized application of fertilizers, we have developed a "full element" compound microbial liquid fertilizer that integrates the quick-acting properties of inorganic fertilizers, the long-acting properties of organic fertilizers, and the synergistic properties of biological bacterial fertilizers, which can realize the integration of water and fertilizer.

Embodiment 1

[0031] 1. Supply of amino acid solution

[0032] Using sulfuric acid with a concentration of 5mol / L, acidolysis the lean meat of sick and dead pigs at 80°C for 6 hours to obtain an amino acid solution; the mass-volume ratio of lean meat to sulfuric acid is 1:1.5.

[0033] 2. Production of functional bacterial agents

[0034]The rhizosphere growth-promoting Bacillus amyloliquefaciens SQR-9 with the preservation number of CGMCC NO.5808 was inoculated into the LB culture solution, and the liquid fermentation production was carried out. ~180 rpm, spores are formed in the middle and late fermentation, so that the amount of bacteria or spores in the fermentation broth is ≥1×10 9 CFU / mL. The preparation method of the LB culture medium used is: take 1000 mL as a column, 5 g of yeast, 10 g of peptone, and 10 g of sodium chloride, dilute to 1000 mL with deionized water, stir evenly, adjust the pH value to 7.0-7.6, and sterilize at 121 °C for 20 min.

[0042] Field test

[0043] 1. Field effect of "full element" compound microbial liquid fertilizer on corn

[0044] This experiment was carried out in Hai'an County, Nantong City, Jiangsu Province. The experiment consisted of three treatments: treatment 1 was a blank control, no liquid fertilizer was applied; treatment 2 was an amino acid liquid fertilizer (urea 100g / L+dihydrogen phosphate) without Bacillus amyloliquefaciens. Potassium 50g / L+amino acid 200mL / L+molasses 200mL / L+deionized water 500mL / L); treatment 3 is the research and development product "Quanyuan" compound microbial liquid fertilizer (urea 100g / L+ dipotassium hydrogen phosphate 50g / L+ amino acid 200mL / L+ Molasses 200mL / L + deionized water 500mL / L + 10% Bacillus amyloliquefaciens SQR-9 fermentation broth), each treatment has 3 plots, plot length 5.25m, width 3m, area 15.75m 2 , the test variety was Suyu No. 29, and all treatment base fertilizers were uniformly fertilized according to the local fertilization met...

Abstract

The present invention provides a multiple compound microbial liquid fertilizer, a preparation method and applications thereof, and belongs to agricultural high-tech production technology. According to the present invention, the multiple compound microbial liquid fertilizer is prepared from an amino acid liquid, urea, molasses, dipotassium hydrogen phosphate, and Bacillus amyloliquefaciens SQR-9 having the preservation number of CGMCC NO.5808 according to a certain ratio, the total nutrient (including the total nitrogen (TN), the total phosphorus (P2O5) and the total potassium (K2O)) is 100%, and the number of functional bacteria is more than or equal to 5*10<8> CFU / mL after storage for 3 months; and the novel fertilizer integrates the rapid effect of the chemical fertilizer, the growth effect of the organic fertilizer, and the synergistic function of the biological fertilizer, further has advantages of good growth promoting effect, low production cost and convenient application, and can be used for grain crops, vegetables, and the like.

Description

technical field [0001] The invention belongs to the field of biological fertilizers, and relates to a "full element" compound microbial liquid fertilizer and a preparation method and application thereof. Background technique [0002] Some developed countries began to enter the stage of agricultural modernization in the 1920s and my country in the 1960s, and adopted the conventional agricultural modernization development model of "high input, high output, and high pollution", which greatly improved the level of agricultural production. At the same time, it also leads to the extreme consumption of resources, the destruction and pollution of the ecological environment. With the development of the chemical fertilizer industry and the increase in the amount of agricultural chemical fertilizers, the output of crops has increased greatly, but while chemical fertilizers have made great contributions to the development of agricultural production, they have also caused a large number o...
